I’d rather trade Mack or Chubb. People love hype and possibility, especially with rookies (Mack is basically a rookie); so, I think you have the depth to trade on hype. That being said, I fully buy Kerryon’s hype and wouldn’t trade him.
I think you can flip Mack or Cubb for an under-performing WR. I would try to pair one of them with a middle tier WR and go after K. Allen.
For example: Chubb and Golladay for Allen
